Question: What is the benefit of electric motor?

What is the main function of an electric motor?

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.

What is the disadvantage of electric motor?

The disadvantages of these motors include the following. Large electric motors are not easily movable, and consideration should be made for the exact voltage and current supply In some situations, expensive line expansions are mandatory for isolated areas where electrical power is not accessible.

What is electric motor explain with diagram?

1) When electric is passed into the rectangular coil, magnetic field is produced around the coil. 2)The magnetic field of horse shoe type interacts with the magnetic field on the coil and causes the coil to rotate continuously.

What are the advantage and disadvantage of electric motors?

Electrical motors are more environmentally-friendly, as they do not cause pollution by burning fossil fuels, which in turn produces harmful greenhouse gases. Electrical motors generally save the end-user money over time, while gasoline engines are more expensive in comparison.

What are the disadvantages of motor?

Induction Motor Disadvantages:

  • 3 phase induction motors have poor starting torque and high have in rush currents. …
  • Induction motors always operate under lagging power factor and during light load conditions they operate at very worst power factor (0.2 to 0.4 lagging).

What is electric motor and its principle?

Electric motor: An electric motor is a device which converts the electrical energy into the mechanical energy. Principle: An electric motor (dc motor) works on the principle that when an electric current is passed through a conductor placed normally in a magnetic field.

What are the main parts of electric motor?

Motor Basics

No matter the type of motor, there are three basic parts: a stator, a commutator, and a rotor. Together they use electromagnetism to cause the motor to spin. As long as the motor receives steady current, the motor works.
